Spherical Powders(球形粉末)研究综述
Spherical Powders 球形粉末 - In this work properties of spherical powders including 304L, 310, 316L and 17-4PH grade were determined using scanning electron microscopy, laser diffraction particle size analysis, reductive melting method and X-ray analysis. [1] A composite porous wick with spherical–dendritic powders is proposed, in which the dendritic powders fill the gap between the spherical powders. [2] The coatings deposited with nonspherical powders are characterized by a fine-grained structure and their micromechanical properties are comparable to those of the coatings deposited with spherical powders. [3] It is shown that the use of non-spherical powders of titanium for additive technologies results in formation of low level of corrosive properties, that requires the realization of additional research in this area. [4] SEM images indicate that the size of MnO2 quasi-spherical powders are in nanoscale and transform into short rod under calcination temperature at 500 °C. [5]在这项工作中，使用扫描电子显微镜、激光衍射粒度分析、还原熔融法和 X 射线分析测定了包括 304L、310、316L 和 17-4PH 级在内的球形粉末的性能。 [1] 提出了一种具有球形-树枝状粉末的复合多孔芯，其中树枝状粉末填充了球形粉末之间的间隙。 [2] 用非球形粉末沉积的涂层具有细晶粒结构的特点，其微观机械性能与用球形粉末沉积的涂层相当。 [3] 结果表明，在添加剂技术中使用非球形钛粉末会导致形成低水平的腐蚀性能，这需要在该领域进行额外的研究。 [4] SEM图像表明，MnO2准球形粉末的尺寸为纳米级，在500°C的煅烧温度下转变为短棒。 [5]
